To all whom t may concern:

Be it known that we, SAMUEL vWinssiiAN and RALPH l'fVnrsMiiN, citizens of the United States of America, residing at Detroit, in

'the' county of Wayne andState of Micliio'an,

have invented certain new and useful mprovements in Side Thrust Supports for Spring-Bed Bottoms, of which the follow-A ing is a speciiication, reference being had therein to the accompanying drawings.

This invention relates to a side thrust suppoi-'t' for spring bed bottoms of that type einployin-g a plurality, of longitudinal and transverse rows of springs secured tol and supported' at their lower ends on a frame 4structure that engages .the siderails of the bed and at their upper ends connected to each other and 'to' side and end members of' which maintain' a dei-ined relation between the side edges 'f the upper rame'o'f the bed bottom and /t e side edges of the bottom frame so that when the side edge of the top frame isl depressed, for instance by being sat upon, the edge of the frame must assume a defined position when returning to normal position. 'Y A y Our invention further aims to provide side thrust' units which will maintain the top frame work or. webbing cfa bed spring taut and prevent depressed portions because of constant use.

Our invention further aims to provide y side thrust supports for a spring bed bottom that may be easily and quickly installed, manufactured at a comparatively small cost, and used without any danger of a mattress or other bed being injured or torn.

Our invention possesses other advantages that may appear as the invention is hereinafter described, and; reference will now be had tothe drawing wherein- Figure l is a, diagrammatic plan of a spring bed bottom with' a longitudinal cen-4,

tral portion thereof broken away, showing only the side portions ot the spring bed bottom AFig. 2 is an enlarged plan of the side por tion of the spring` bed bottom;

Fig. 3 is a side elevation of a side thrust support in. accordance with our invention;

Fig. 4 shows views, on a small scale, of a modified form. of side thrust support;

Fig. 5 is a perspective view of a portion of .onevoi the members of the side thrust support, and

Fig. 6. is a similar view of a further modiiic'ation oiu our invention.

rlhe spring bed bottom shown in the draw- A' i ings comprises a lower frame l that may -be` made of channel or angle iron and the side rails 2 of the trame are connected by trans-v verse spring supporting members 3 on which are mounted and suitably secured the lower convolutions ot springs 4, said springs having` the upper convolutions thereof suitably connected together by members 5 within an upper frame 6 which is held in spaced relation to the lower frame' 1 by thelexpansive force of the springs t. The upper frame 6`4 may be made of wire or any suitablefmate* rial that will aii'ord a substantial edge for the upper portion oi? the spring; bed bottom.

The springr support-ingr members 3 may be conveniently'considered as being in sets with the members oi each set connected by longitudinally disposed bars 'Y and each bar, intermediate its ends is connected to the rail 2 by an inclined base piece S. said base piece and said bar being preferably made of metallic straps having` the endsl thereot bent or twisted for attachment to the members 3 and the rail 2 by rivets or other fastening means. The bar 7 is necessarily set at an anglerso that the hase piece S may extend upwardly at an inclination to the plane of the dropped portions of the spring supports 3.

.As an instance of other fastening means, than rivets` we show in Fig. 6 a bar 7 having hooked shaped end tongues 2 extending;l

into openings 3a in the supports 3 and the lower end of the base piece 8 has a tongue 8ek extending, into an opening of the barI 7a. Whenthe supports 3 and base piece` 8 are in position, the tongues will hold the parts assembled". Pivotally connected to a side wall of the iio base piece 3, vby rivets 9 or other pivotal'y means, are the lower ends of link members
